T 0 all whom it may concern: 7

Be it known that I, EDWARD AsA'BuRrEn, a citizen of the United States, residing at Benton, in the county of King'and State of lVashington, have invented a new and useful Tool for Restoring a Swage-Bit to Good Condition After the Lips Thereof Have Been Bent and Otherwise Injured, of which the following is aspecification.

My .invention relates make the bent and injured lips of such bit straightening and restoring said bent lip and straight and renew the original utility of,

said bit, and second, to save the money required to buy a new blt.

I attain these ob ects by the mechanism illustrated in the accompanying drawing, in-

Which- Figure 1 is anindependent view of said Fig. 2 is theboring part of a swage-bit, one of whose lips has been bent and impaired by striking a nail or other hard substance, together; with the position invention, and

and angle of said invented tool for use in bit to good condition and gage.

As the invention consists of but one part,

7 the numbers of the figures only are shown in r V V adjustable to said lips both when the latter the several views.

Fig. l is a hard metal bar, preferably steel, curved and concave at one end behind which and through which bar is an elliptical hole fitting loosely, when in use, over the screw and point of said bit making said curvedand concave end adjustable to either 7 of said lipsbothwhe'n' the latter are bent and in normal position, and which bar thence tapers to its other end and is "of suitable; dimensions for convenient use.

J 3 person with a hammer may usethe tool the size of the bit,

bit, after much usage, will lose their keen .50 forthe purposestated. In" the manufacture of said tool, its size should correspond tocutting quality with moreorless loss of gage on clearance, inv which casethe use. of said 4 tool anda whet stone will restore this lost quality, when without such tool the bit -would remain worthless; V 1" i Having thus described andillustrated my invention, I claim A tool for use in restoring togoo d work ing condition a swage-bit whose .lipsor. lip have been bent and otherwise impa1red,'said tool being a hard metal bar curved and con cave at oneend thereofibehind which end and throughwhich baris an elliptical'hole that'fits looselyrover'the screw and pointiof 7 saidjbit, making said curved and concave end are-bent and in normal position, and which bar thence tapersto its other endand is of sultabledlmensionsfor conven ent use, 'substantiallyfas described and shown."
